Junction box assembly

Abstract

A junction box assembly includes a main body on which an electric circuit is disposed having at least one socket electrically connected to the electric circuit. A first cover covers a surface of the main body on which the electric circuit is disposed. A second cover covers another surface of the main body opposite the first surface and has a connector corresponding to the at least one socket. A coupling unit fastens the main body and the second cover together by a sliding motion thereof, such that the socket and the connector are coupled to each other.
